The avenue of the Catthedral which links the Plaça Nova to the Via Laietana, is a wide promenade - a haven for skaters - running all the way to the flight of steps in front of the cathedral, before the Pla de la Seu. This square, built in 1421, is famous for the «Fira de Santa Llúcia», which takes place every year on the 8th December at which locals buy all sorts of the accessories for the Christmas crib. The square is surrounded by two beautiful houses, Casa de la Canonja and Casa de l'Ardiaca.
